They have? Thats pretty awesome, I hope the same guys are there that have done the install. Do you or can you get the guy/s name that did the install?

I was gonna start asking around who in Miami/Ft Lauderdale would be able to do this. I don't know anybody down here that has installed headers on a F

 

I have the PPE headers, and i have 0 problems, buti will say this, any aftermarket exhaust with the headers will be loud, but it's a very refined loud, unlike the LSX engines, imo

but which ever you choose your butt dyno will really be able to tell, lol

 

Hey guys....here's the link to our fresh GB on SIKKY headers AND sway bars
https://www.clublexus.com/forums/clu...ml#post7205303

 

Contact jc or tony at jm customs

I've dealt with jc for all my installs. Great guys.

 

Hey Theo your right I'm currently running PPE Headers with 200 cell Hi flow cat Joe Z exhaust and Intake to me my F is slightly louder when driving aggressively and yes louder at WOT but overall not huge difference between when I had just JoeZ exhaust and Intake only so when driving normaly IMO its about same as Joe Z exhaust and intake set up just little louder. I think it has to do with 200 cell Hi Flow cat. I drove in another CL members with similar set up only difference was he had 100 cell Hi-flow cat his cars was little louder then my current set up. I may add Test pipe to this set up for track days will keep you posted.

 

I have had sikky headers with Joe z for almost 2 years and about 16k. not one complaint, in fact much praise and I have put the parts threw hours of track abuse... I made 60 wheel and have never had a check engine light or a rattle.. Props to silly and JE "sikky headquarters"

 

Aw man i think im down for this gb also, but don't have any shops in mind for the install. Anyone their headers installed that live in the bay area?have

 

Figs has started his GB for PPE headers here:

Both RHD and LHD. No Dipstick relocation with the redesigned header Come on folks - You know you want 'em

In my honest opinion.

PPE vs SIKKY is basically aesthetics (PPE) vs better performance (SIKKY)

Does anyone care to do a back to back testing on PPE vs SIKKY dyno gains?

 

Where are you pulling this out of?

 

Emails to them are bouncing back so I called, they have my number and will call back once they have a price on hand, hopefully later today.

 

My friend you are dead wrong! The performance of the two headers is comparable. Aesthetics is not the issue but workmanship is. As far as output goes. I am attaching two graphs. The first graph shows my car with PPE, Hi-Flow Cats and a custom dual exhaust system utilizing stock mufflers. It shows 386+ HP. The other F is a friend's with PPE, no cats, and a JoeZ exhaust. It shows 399+ rear wheel HP.

The second graph shows a stock F and works it's way up to an F with Sikky headers and a JoeZ exhaust. I believe this car also had H-Flow Cats. It shows 385+ HP.

It should be noted that these cars were run on the same type of Dyno under similar conditions. It should also be noted that the PPE does not show a dip at 5200 RPM like the Sikky does

I agree power between the two are pretty much on par. With regards to craftsmanship differences I could care less what they look like since they are well out of sight. I have yet to hear of any craftsmanship issues with either of the two brands. It really does come down to personal preference as you really can't go wrong with either.

Anyway the second chart posted above by Lou is valid, but wanted to share my most recent dynojet graph with SIKKY headers used in conjunction with Borla exhaust and the stock intake. The 400+ whp run was not a fluke run as I had 3 consecutive runs over the 400whp mark.


No dip at 5200 below.

 

^^^^No cats I assume.

I had PPE header before on my IS350, quality and customer service were great . they are very compatible.. Just that PPE group buy were a bit late.... thump up for both headers .
